H&W Investigations, tome 6 : Enslaved By the Others
Jess Haines2014

Vampires, werewolves, magi and worse--the Others have joined the mortal world, and there's no turning back now...

As a New York P.I. and Other specialist, Shiarra Waynest has been in plenty of trouble before. But waking up in a windowless room the prisoner of a vampire slave trader is a shock for anyone. Shia has her wits, her bravado, and a couple of used staples, so maybe she can take on a mansion full of serious evil.

But although she's desperate to escape, Shia needs some answers too. Her friends are in danger. There are betrayers and spies among them. And even if she can figure out what's going on and somehow get a message out, she's still a captive of the worst kind...
